@awinkler This already seems to be working on https://www.museum-digital.de, provided that the identifiers for people (museum-digital-ID), places (museum-digital-Ort-ID) and subjects/keywords (museum-digital-Tag-Kennung) have been entered in #Wikidata. At the object level, this would be a nice-to-have feature. @jrenslin
